  • Biau, Emmanuel, 1985-; Morís Fernández, Luis, 1982-; Holle, Henning; Ávila, César; Soto-Faraco, Salvador, 1970- (Elsevier, 2016)
    During public addresses, speakers accompany their discourse with spontaneous hand gestures (beats) that are tightly synchronized with the prosodic contour of the discourse. It has been proposed that speech and beat gestures ...
  • Vázquez, Toni Adame; Barrachina Muñoz, Sergio; Bellalta, Boris; Bel, Albert (MDPI, 2018)
    The emergence of low-power wide area networks (LPWANs) as a new agent in the Internet of Things (IoT) will result in the incorporation into the digital world of low-automated processes from a wide variety of sectors. The ...
  • Batard, Thomas; Bertalmío, Marcelo (Springer, 2014)
    We present a method to perform histogram matching be- tween two color images based on the concept of harmonic mapping be- tween Riemannian manifolds. The key idea is to associate the histogram of a color image to a Riemannian ...
  • Roelleke, Thomas; Kaltenbrunner, Andreas; Baeza Yates, Ricardo (Oxford University Press, 2014)
    In many applications, independence of event occurrences is assumed, even if there is evidence for dependence. Capturing dependence leads to complex models, and even if the complex models were superior, they fail to beat ...
  • Manathunga, Kalpani; Hernández Leo, Davinia (International Forum of Educational Technology & Society, 2015)
    There is a growing interest in understanding to what extent innovative educational technologies can be used to/nsupport massive courses. Collaboration is one of the main desired elements in massive learning actions/ninvolving ...
  • Derkach, Dmytro; Ruiz Ovejero, Adrià; Sukno, Federico Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    In this paper we present a system that is able to estimate head pose using only depth information from consumer RGB-D cameras such as Kinect 2. In contrast to most approaches addressing this problem, we do not rely on ...
  • Ortigosa, Núria; Rodriguez López, Mérida; Bailón, Raquel; Sarvari, Sebastian Imre; Sitges, Marta; Gratacós Solsona, Eduard; Bijnens, Bart; Crispi Brillas, Fàtima; Laguna, Pablo (Elsevier, 2016)
    Intrauterine Growth Restriction (IUGR) and premature birth are associated with higher risk of cardiovascular diseases throughout adulthood. The aim of this study was to evaluate the influence of these factors in ventricular ...
  • Hernández Leo, Davinia; Agostinho, Shirley; Beardsley, Marc; Bennet, Sue; Lockyer, Lori (IATED, 2017)
    Designing learning experiences for students is a key responsibility of teachers. This involves designing stimulating and engaging tasks, selecting and creating appropriate resources, and deciding how best to support students ...
  • Kolobov, Andrey; Mausam; Weld, Daniel S.; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Research in efficient methods for solving infinite-horizon MDPs has so far concentrated primarily on discounted MDPs and the more general stochastic shortest path problems (SSPs). These are MDPs with 1) an optimal value ...
  • Bonet, Blai; Geffner, Héctor (Elsevier, 2008)
    The automatic derivation of heuristic functions for guiding the search for plans is a fundamental technique in planning. The type of heuristics that have been considered so far, however, deal only with simple planning ...
  • Angulo, Iñigo; Giraldo, Sergio; Ramírez, Rafael,1966- (Anglia Ruskin University, 2016)
    Music representation has been a widely researched topic through centuries. Transcription of music through the conventional notation system has dominated the field, for the best part of the last centuries. However, this ...
  • Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Finite State Controllers (FSCs) are an effective way/nto represent sequential plans compactly. By imposing/nappropriate conditions on transitions, FSCs/ncan also represent generalized plans that solve a/nrange of planning ...
  • Sanabria Russo, Luis; Barceló Vicens, Jaume; Bellalta, Boris; Gringoli, Francesco (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Collisions are a main cause of throughput degradation in wireless local area networks. The current contention mechanism used in the IEEE 802.11 networks is called carrier sense multiple access with collision avoidance ...
  • Gil Rodríguez, Raquel; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    In this paper we present a simple and affordable method to generate high quality video from a high dynamic range scene. It is performed without utilizing extra lighting, neither alternating exposures, nor operating with ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Benton, David M. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This article proposes a frequency agile antenna whose operating frequency band can be switched. The design is based on a Vivaldi antenna. High-performance radio-frequency microelectromechanical system (RF-MEMS) switches ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Brittan, P. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band ...
  • Montesinos, P.; Abascal, Juan F.P.J.; Chamorro Servent, Judit; Chavarrías, Cristina; Benito, M.; Vaquero, Juan J.; Desco, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2011)
    Dynamic cardiac magnetic resonance imaging in small animals is an important tool in the study of cardiovascular diseases. The reduction of the long acquisition times required for cardiovascular applications is crucial to ...
  • Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. Our main goal is to determine the performance loss caused by the need for estimating the ...
  • Lozano Solsona, Angel; Tulino, Antonia M.; Verdú, Sergio (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    The analysis of the multiantenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative /nincrease as function of the number of antennas. ...
  • Levkov, Klimentiy; Linzon, Yoav; Mercadal, Borja; Ivorra Cano, Antoni, 1974-; González, César Antonio; Golberg, Alexander (Elsevier, 2020)
    Optimization of protocols is required for each specific type of biomass processed by electroporation of the cell membrane with high voltage pulsed electric fields (PEF). Such optimization requires convenient and adaptable ...
